2021-03-30mmc: sdhci-pci-o2micro: Add missing checks in sdhci_pci_o2_probeDinghao Liu
It's odd to adopt different error handling on failure of pci_read_config_dword(). Check the return value and terminate execution flow on failure of all pci_read_config_dword() calls in this function.

2021-03-30mmc: core: Drop reference counting of the bus_opsUlf Hansson
When the mmc_rescan work is enabled for execution (host->rescan_disable), it's the only instance per mmc host that is allowed to set/clear the host->bus_ops pointer. Besides the mmc_rescan work, there are a couple of scenarios when the host->bus_ops pointer may be accessed. Typically, those can be described as as below: *) Upper mmc driver layers (like the mmc block device driver or an SDIO functional driver) needs to execute a host->bus_ops callback. This can be considered as safe without having to use some special locking mechanism, because they operate on top of the struct mmc_card. As long as there is a card to operate upon, the mmc core guarantees that there is a host->bus_ops assigned as well. Note that, upper layer mmc drivers are of course responsible to clean up from themselves from their ->remove() callbacks, otherwise things would fall apart anyways. **) Via the mmc host instance, we may need to force a removal of an inserted mmc card. This happens when a mmc host driver gets unbind, for example. In this case, we protect the host->bus_ops pointer from concurrent accesses, by disabling the mmc_rescan work upfront (host->rescan_disable). See mmc_stop_host() for example. This said, it seems like the reference counting of the host->bus_ops pointer at some point have become superfluous. As this is an old mechanism of the mmc core, it a bit difficult to digest the history of when that could have happened. However, let's drop the reference counting to avoid unnecessary code-paths and lockings.

2021-03-30mmc: core: Drop superfluous validations in mmc_hw|sw_reset()Ulf Hansson
The mmc_hw|sw_reset() APIs are designed to be called solely from upper layers, which means drivers that operates on top of the struct mmc_card, like the mmc block device driver and an SDIO functional driver. Additionally, as long as the struct mmc_host has a valid pointer to a struct mmc_card, the corresponding host->bus_ops pointer stays valid and assigned.

2021-03-30mmc: core: Do a power cycle when the CMD11 failsDooHyun Hwang
A CMD11 is sent to the SD/SDIO card to start the voltage switch procedure into 1.8V I/O. According to the SD spec a power cycle is needed of the card, if it turns out that the CMD11 fails. Let's fix this, to allow a retry of the initialization without the voltage switch, to succeed. Note that, whether it makes sense to also retry with the voltage switch after the power cycle is a bit more difficult to know. At this point, we treat it like the CMD11 isn't supported and therefore we skip it when retrying.

2021-03-26smb3: fix cached file size problems in duplicate extents (reflink)Steve French
There were two problems (one of which could cause data corruption) that were noticed with duplicate extents (ie reflink) when debugging why various xfstests were being incorrectly skipped (e.g. generic/138, generic/140, generic/142). First, we were not updating the file size locally in the cache when extending a file due to reflink (it would refresh after actimeo expires) but xfstest was checking the size immediately which was still 0 so caused the test to be skipped. Second, we were setting the target file size (which could shrink the file) in all cases to the end of the reflinked range rather than only setting the target file size when reflink would extend the file.

2021-03-26cifs: revalidate mapping when we open files for SMB1 POSIXRonnie Sahlberg
RHBZ: 1933527 Under SMB1 + POSIX, if an inode is reused on a server after we have read and cached a part of a file, when we then open the new file with the re-cycled inode there is a chance that we may serve the old data out of cache to the application. This only happens for SMB1 (deprecated) and when posix are used. The simplest solution to avoid this race is to force a revalidate on smb1-posix open.

2021-03-26kernel: don't call do_exit() for PF_IO_WORKER threadsJens Axboe
Right now we're never calling get_signal() from PF_IO_WORKER threads, but in preparation for doing so, don't handle a fatal signal for them. The workers have state they need to cleanup when exiting, so just return instead of calling do_exit() on their behalf. The threads themselves will detect a fatal signal and do proper shutdown.

2021-03-26dm ioctl: fix out of bounds array access when no devicesMikulas Patocka
If there are not any dm devices, we need to zero the "dev" argument in the first structure dm_name_list. However, this can cause out of bounds write, because the "needed" variable is zero and len may be less than eight. Fix this bug by reporting DM_BUFFER_FULL_FLAG if the result buffer is too small to hold the "nl->dev" value.
